Title: Storage element for the permanent storage of digital information
IPC: H01L29/00
Filed: 1975-08-27
Abstract: 1469919 Semi-conductor storage elements BATELLE-INSTITUT EV 27 Aug 1975 [27 Aug 1974] 35402/75 Heading H1K An element for permanently storing digital information comprises an electret film with a thin-film FET directly applied to one surface and a glow discharge gap adjacent the other, whereby the charge condition on the gap, adjacent surface of the electret and thus the conductivity of the semi-conductor channel layer of the FET or the opposite surface is determined by the polarity of the voltage sufficient to cause a discharge last applied across the gap. A storage matrix may comprise a co-ordinate array of such elements on a common electret film, e.g. of polyfluoroethylene propylene, utilizing 200 Š thick films of tellurium, tin oxide or lead sulphide with a doping of 0À5 Î 10<SP>18</SP> cm.<SP>-3</SP> and a gate insulation thickness of 500 Š in the FETs, thus enabling the channels to be blocked at a gate voltage of 2 volts. Glow discharge gaps are located at the crossings of perpendicularly arranged sets of electrodes 8, 9 (Fig. 4) to permit random access for storage and erasure by a coincidence switching arrangement. Series connection of the source-drain paths of the FETs in each row and parallel connection of the gates in each column enables randomaccess read-out via associated selector matrices independently of recording and erasure. As many as 10<SP>4</SP> elements may be included in a row if the on-off resistance ratio of the FET channels is 10<SP>5</SP> : 1.

Title: Fluid port construction for pressure vessels
IPC: F15B1/18
Filed: 1958-11-04
Abstract: 902,151. Hydraulic accumulators. MERCIER, J. Nov. 4, 1958, No. 35418/58. Class 69 (2). A fluid port 14 in an hydraulic accumulator having a rigid container 11, Fig. 1, in which is a deformable partition 12 movable against the port comprises a multiplicity of openings 17 through a member or part 16 of the container, and a coating 26 of resilient material on the top surface of the member or part and the wall surfaces of the openings, the coatings on all the surfaces being integral with each other. The openings may be formed in the curved or flattened end 16 of the container which may be spherical or cylindro-spherical, of steel, cast aluminium or the like, and has welded thereto a sleeve 21 for connection to the hydraulic system. The end of the container has the openings 17 punched therethrough and is coated with a resilient material, such as rubber, preferably by dipping into a vat so that, on withdrawal, the rubber forms conical projections 32, Fig. 2, which aid the flow of liquid into the container. The rubber is vulcanized to aid setting. When the bladder expands, it bears against the resilient coating which deforms to close or substantially close the openings and prevent damage to the bladder by its extending into the openings. In another embodiment, a sleeve 41, Fig. 3, is secured to a bore in the container by a nut 43 and has a wall 46 at one end in which are openings 47. A wire mesh screen 49, the individual wires of which are coated with resilient material, is seated in a recess in the sleeve. The above constructions may be applied to both the gas and liquid ports 13, 14 of the accumulator.

Title: Raster Distortion Correction Circuit
Inventor: KRAMER DON ANTHONY
IPC: H04N3/18
Filed: 1968-07-25
Abstract: 1,198,209. Cathode-ray tube circuits. MOTOROLA Inc. 25 July, 1968 [14 Aug., 1967], No. 35431/68. Heading H4T. In an arrangement for correcting vertical pin-cushion distortion in the raster on a cathoderay display tube by coupling a correction waveform into the vertical deflection circuit the waveform is produced under the control of two trains of pulses of horizontal repetition frequency and opposite phases. The pulse trains 66, 68 (Fig. 1) are derived from the horizontal scan transformer 22 and supplied via respective capacitors 62, 64 and resistors 74, 78 to respective diodes 76, 80 which are rendered progressively more conductive (diode 76) and less conductive (diode 80) by a sawtooth wave 60 (derived via an integrating circuit 58 from the waveform 54 at the output of the vertical deflection. amplifier 40) so that an increasing and decreasing portion of the two pulse trains respectively is shunted to earth via circuit 58 centered about zero potential as shown at 82 and 84. The latter pulse trains are then applied to respective diodes 94, 98 and the transmitted pulse trains 96, 100 combined via respective amplitude control adjustable resistors 102, 104. The combined output at the junction of the latter resistors is then supplied to an L.C. circuit 106, 108 resonant at the horizontal frequency and via resistor 112 capacitor 114 and triode 116 to the primary winding of a transformer 120 the secondary 122 of which resonates at the horizontal frequency and is connected to the vertical deflection coils 50, 52. L.C. circuit 106, 108 produces a sinusoidal voltage waveform 110 (this being a sufficiently close approximation to the ideal parabolic correction waveform) having the required decreasing and increasing amplitude characteristic with a reversal of phase between the two portions but since the pulse trains which cause circuit 106, 108 to ring to produce the waveform occur during line retrace intervals it is necessary to change the phase of waveform 110 by 180 degrees so that the correction is effected during the trace periods. This phase change is produced in two stages, the first being on 90 degree phase shift produced by inductance 106 together with resistor 112 and capacitor 114 and the second an additional 90 degree phase shift produced by the action of the vertical deflection coils 50, 52 in converting the voltage waveform 110 into current counterpart. The latter is thus combined with the normal sawtooth deflection current 53 and provides the waveform required for correction of pincushion distortion of the kind shown in Fig. 2.

Title: Process for the production of ú´-hydroxy-azo-naphthalenic compounds
IPC: C09B27/00
Filed: 1960-10-24
Abstract: o-Hydroxy azo compounds are made by treating a diazotate, in solution or suspension, with a diazonium compound, at least one of the starting components being of the naphthalene series.  It is stated that some of the products are new.  Reaction is usually effected in a distinctly alkaline solution, e.g. pH 9-12, but may, with some diazotates, occur at pH's of 5-9.  Stoichiometrical proportions of reactants are normally used.  From a diazotate R-N=N-O(-), and a 1-diazonaphthalene compound, a 2-naphthol dye of formula <FORM:0929052/IV(a)/1> is obtained, a 2-diazonaphthalene compound yielding a 1-naphthol of formula <FORM:0929052/IV(a)/2> By-products may be obtained from the action of the alkali on the diazo compound, e.g. <FORM:0929052/IV(a)/3> and <FORM:0929052/IV(a)/4> The by-products may be isolated or redissolved and their production controlled by varying the proportions of diazotate and diazonium compound.  From a diazonium compound <FORM:0929052/IV(a)/5> and a diazotate of the naphthalene series, similar dyes are obtained.  With some of the 1-naphthol azo dyes thus obtained a second azo group may, by a secondary reaction, enter the molecule in a para position to the resulting hydroxy group.  The second coupling may be counteracted by varying the proportions of diazotate and diazonium compound.  The diazotates may be derived from carbo- and heterocyclic diazo compounds.  Derivatives of benzene, naphthalene, anthracene and dehydrothiotoluidine disulphonic acid are mentioned.  Substituents, e.g. sulphonic and carboxylic acid, benzenesulphonate, alkyl, nitro, acylamino, halogen and azo groups, may be present in the diazotates. Advantageously syn-diazotates are used.  Specified diazotates include 4-sulphophenyl-syn-and anti and 4-nitro-, 2,5-dichloro-and 2-methoxy-4-nitro-phenyl-anti-diazotates.  The diazotates need not be used in the isolated form.  Thus the diazonium compounds, from which they are derived, may be converted, in situ, to diazotates by treatment with sodium carbonate or hydroxide.  Illustrative of diazo compounds, to be so treated, are those derived from aniline, 4-benzoylamino-aniline, 4-aminoazobenzene-41-sulphonic acid, dehydrothiotoluidine-disulphonic acid, 6-nitro-2-naphthylamine-4,8-disulphonic acid and 1-aminoanthraquinone.  Diazonium compounds specified include aniline, 4-nitroaniline, 2-naphthylamine-4-sulphonic and 3-carboxylic acids, 1-naphthylamine-3,6,8-trisulphonic acid, 1-aminoanthraquinone, 4-aminoazobenzene-41-sulphonic acid and 8-aminoquinoline-5-sulphonic acid.  Numerous examples are provided of the preparation of the dyes, a variety of colours being obtained, and their use in dyeing wool.

Abstract: 1,123,776. Speedometers. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Aug. 4, 1967 [Aug. 16, 1966], No.36602/66. Heading G1K. Apparatus for measuring the speed of rotation of a shaft 1 comprises a member 3 towards a surface of which is directed a nozzle 13 supplied with fluid under pressure, the pressure of the fluid at the nozzle being dependent on the distance between the nozzle and the surface, which distance in turn depends on the rotation speed of the shaft so that this speed may be determined by measuring the fluid pressure at a point 15 adjacent the nozzle. Rotation of the shaft 1 is transmitted to a carrier 5 by a gear train 4, bell crank levers 7 having fly weights 8 being pivotally mounted on the carrier. Centrifugal force causes the levers to pivot about their fulcra 6 and upwardly urge a shaft 12 against the pressure of a spring 10. Instead of being frusto conical the surface of the member 3 may have other shapes to provide a non-linear relationship between the pressure measured at the point 15 and the rotation speed of the shaft. Alternatively, the nozzle 13 may rotate with the shaft 12 and the member 3 may be fixed. In a second embodiment, the nozzle is mounted directly below an end face of a spring-loaded tubular member attached to the end of the shaft 12.
